As a bodybuilder who is also used to specific nutrition to maintain physical shape: there is nothing wrong with that meal posted on the first page. It isn't "substandard" at all.
Is it appetizing looking? No. Is it award-winning cuisine? Also no.
But I'll break it down for you:
Garden greens with arugula (dark leafy green), watermelon (carbs), goat cheese (protein)
Caprese salad (calorie dense thanks to the cheese, plus protein - this is often a go-to of mine in a pinch)
Italian grilled chicken (protein)
White fish (protein)
Parmesan polenta (carbs and calories)
Pasta with Impossible bolognese sauce (big time carbs, big time calories, and protein from the bolognese)
Roasted summer vegetables (veggies, obviously)
This is actually a crap ton of food (clearly intentional, as they likely consume a very high amount of calories), a lot of protein, a lot of carbs, and a lot of sodium (which endurance athletes need). The picture posted on shows the salad, fruit, and a snack (appears to be two varieties of chips - high carb), not the full meal. All of these items on that list and in that photo are the kinds of things an athlete would eat in a tight situation where meal prep wasn't possible. I've done similar when I didn't have time to meal prep (although I've never eaten both chicken and fish in a single meal, but these men are also much bigger than me).
A top-level athlete can handle eating salad from a plastic container and some bland grilled chicken for 14 days. Their physiques are not so fragile that being unable to eat filet mignon and swordfish for two weeks will cause them to fall apart or perform poorly, I assure you. As long as they are getting the calories they need, they will be fine.
